Android: Low Light Theme Switcher

This helper library will automatically switches your Activity between Dark/Light themes using the device light sensor and DayNight theme from Support Library 23.2.

The DayNight theme available in Support Library is a really neat feature, but functionally it's not that useful. Even though it's night by time definition, I could still be in a well lit room and it would still show me the night theme.

I beleive that this default behaviour is due to a limitation that not all Android devices will have a light sensor. If the target device does not have a light sensor then it simply falls back to the default behaviour of AppCompatDelegate.MODE_NIGHT_AUTO.

Requires API 14+.

Adding it to your project

Add the jitpack repo to your project build.gradle

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Add the library to your module build.gradle

dependencies {
        compile 'com.github.twig:android-low-light-theme-switcher:1.0.1'
}

Usage

public class YourApplication extends Application {
    @Override
    public void onCreate() {
    super.onCreate();


// Change between day/night/auto
DayNightSensor.start(this);

}
@Override
  public void onTerminate() {
    DayNightSensor.stop(this);
    super.onTerminate();
  }
}</pre> 
   Options
 
   DayNightSensor.start(this, [samplingDelay=3000]);
 
By default, it checks the light sensor values every 3 seconds. If needed, you can adjust this to your liking.
 
   Technical details
 
 
 
Calls Activity.recreate() when a change in brightness is detected.

Make sure that your Activity saves and restores instance state data correctly.
